Abstract: A bird deterrent device with a component which is set up to be arranged at a building envelope, and at which a lenticular image at least partially covers a visible surface is provided. Further, provided is an arrangement with a building envelope and a bird deterrent device which is arranged at the building envelope.

Abstract: Viewfinders for indicia-readers and/or mobile devices running indicia reading applications allow a user to position the reader with respect to the indicia. A display presents a real-time image of the camera as a background, while simultaneously presenting a graphical overlay that is superimposed on the background. The graphical overlay provides a user messages via text or graphics. Choosing a single color for the messages on the graphical overlay can lead to visibility problems in some imaging scenarios. The present invention provides a method and device to provide automatic contrast adjustment of these message based on the image characteristics beneath or around each message in order to maintain visibility in all imaging scenarios.

Abstract: This invention discloses a machine for automatically attaching an optical filter to a lens. The machine includes lens table for supporting the lens. The machine further includes an attachment-medium dispenser system for dispensing a plurality of gapped-dots of an attachment-medium on a top surface of the lens along a peripheral line substantially according to a bottom-surface shape of the filter. The machine further includes a surface-mounting system for mounting the optical filter onto the top surface of the lens for stamping the gapped-dots into a continuous peripheral attachment-seal for attaching the filter to the lens and for sealing a peripheral interface-edge between the filter and the lens.

Abstract: The invention is an illumination unit for point illumination of a medium where at least one light emitter is arranged to illuminate at least one illumination face via a first lens arrangement and a microshutter arrangement. The lens arrangement has at least one microlens arranged with respect to each microshutter so that light emitted from the light emitter is focused on or in the vicinity of the optical axis of the light channel of the individual microshutters. The fed coherent light from the light emitters is modulated by the microshutters onto the illumination face.

Abstract: The present invention discloses a light control means in a stepper.The light control means of the present invention has a twofold structure consisted of at least more than two blades which open a circuit pattern designed on a reticle; and a subblade which can close selectively a portion of the circuit pattern. The sub-blade is mounted above or below one of the at least more than two blades, and is movable in every directions in response to the instruction from the blade control system.Accordingly, the present invention provides a exposure process which can selectively cover only the dies that will be overlapped with the EBR gap of the wafer using sub-blade, thereby increasing the number of the net-die.

Abstract: A device for printing color photographs on photosensitive paper having a segmented filter positioned relative to an inverting and focusing lens at a point where an original image projected through the lens at the paper is inverted. The segmented filter has colored segments corresponding to the primary colors to which the photosensitive paper is sensitive. The colored segments each have a surface area in a ratio corresponding to the relative sensitivity of the paper to the color of the segment. In an alternate embodiment, the filter has equal sized colored components and is moved with respect to an optical axis of the lens to adjust the intensity of each filtered monochromatic image projected onto the paper.

Abstract: An exposure device for a color copying apparatus having a filter holding frame mounting a filter plate provided with color filter layers and a transparent section and a pair of aperture plates for forming a variable aperture. The filter holding frame is movable in a first direction perpendicular to an exposure light path to selectively place the filter layer and transparent section into the exposure light path. The aperture plates are movable toward and away from each other in a direction perpendicular to the first direction and to the exposure light path so as to vary the size of aperture formed therebetween. Between the filter holding frame and the pair of aperture plates there is a mechanism comprising pins and cam grooves for relative movement of the filter holding frame and the aperture plates.

Abstract: The invention relates to a process and an equipment for making color enlaments in additive method, where the device can be fitted onto the traditional enlargers. By using the solution according to the invention the arrangement of the additive color filters under the lens of the enlarger can be solved in a stable but not containing manner, simultaneously ensuring easy and alternating actuating and integration of the colors of the negative. By means of the comparative process, by using the color-analyzer mask and the properly dark colored reference standards belong to the equipment, the color and density balance of the prints to be enlarged can be adjusted by the way of one single trial development, independent of the individual subjective color perceptional ability.

Abstract: The provision in front of the image surface of a photosensitive element of a device that selectively directs image light with increased intensity to microscopic, spaced-apart portions of the image surface yields a photograph or like record having a selectively decreased contrast. The photograph is viewed independently of its location relative to the light directing device. Changing the apparent aperture through which image light reaches the light-directing device can control the amount of contrast decrease. Further, selective filtering of a portion of the incident light separately controls the contrast of high-exposure portions of the image.
